NASAL SUCTION-PUMP.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed April 29, 1916. Serial No. 94,352.

To all whom 'it may concern.'

Be it known that T, FRANK W. PETERSON, a citizen of the United States,residing at Minneapolis, in the count-y of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in NasalSuction-Pumps, of which the following is a specification.

My invention relates to nasal suction pumps used for withdrawing thedischarge from the nose when the patientis unable to perform this dutyin theV natural manner on. cold in the head and other similaraftlictions, and has for an object to provide a stiff bulb attached to asuction head capable ot' being inserted into the nostril. A furtherobject is to form the suction head with a countersunk opening which willin all positions remain remote from the mucous membrane within thenostril and so not cause any pain or irritation to the patient throughimproper' application of the device. A further object is to provide thebulb with a large opening communicating with the suction head, to permitthe easy cleaning of the device. A further object is to form the bulbwith thickened walls to cause the same to be more stii and have apositive action.

The full objects and advantages of my invention will appear inconnection with the detailed description thereof and are particularlypointed out in the claims.

In the drawings, illustratingthe application of my invention m oneform,-

Figure 1 is a. longitudinal sectional view of a suction pump embodyingmy improvements. Fig. 2 is a view similar to Fig. 1 of a modified formof pump. Fig. 3 is a view similar to Fig. 1 ot a still different form ofsuction pump.

My preferred form of pump is clearly shown in Fig. 1. A spherical bulb10 is provided having thick walls 11 formed of stiii rubber which, whendistorted, will quickly return to its original position. The top of thebulb at 12 is formed with internal threads 35 to receive a glass, hardrubber or metal neck 13 which is provided with an enlarged sleeveportion 14 having a {iange member 15 and corresponding threads 16engaging the bulb portion 12 as clearly indi-` cated in the drawings. Bythis means the bulb 10 can easily be removed or attached to the stem tofacilitate cleaning. In view of the said last-named project the openinginto the bulb 10 through the portion 12 is made large enough so that apersons finger or a suitable brush may be inserted into the bulb throughthe aperture. The stem 13 is preferably formed narrow and short andterminates in a substantially spherical head 17 somewhat larger indiameter than the nostril to which it is to be applied. This head isprovided with an aperture 18 the walls 19 of which are sunk into thespherical head 17 to form a countersunk opening into said device. Thesides 2O oi bulb 10 are formed thicker than the remainder of the wall11, so that as the bulb is pressed upward the same tends to quickly andeliectively return to its original position causing a positive action inthe device. The lower portion 21 of the bulb may be made flat on thebottom thereot` so that the device will easily stand on end.

The method of using the device is as follows: The bulb 10 is distortedor collapsed in the usual manner by pressing the bottom 21 inward withthe thumb. One nostril is then closed by a finger of the other hand andthe spherical head 17 inserted into the open nostril. It is notintended, however, that head 17 be positioned entirely within thenostril as suction would hence only cause the device to be drawn fartherinto it. By swallowing` or by pronouncing certain letters the valvecommunicating between the nasal passages and the mouth can be made toclose, and when such a condition is procured the bulb 10 is released.This causes a vacuum in the nasal passages which draws out thedischarges from the glands in said passages into the bulb 10, completelyremoving the same without effort on the part of the patient. 1n caseswhere such a device is used the mucous membrane is usually sore andtender. It the opening in thehead 17 could be placed directly in contactwith any portion of the mucous membrane, the same would tend to be drawninto the head, which would eiiect severe pain and discomfort. With thecountersunk opening such a condition is entirely eliminated since thedevice would have to be at right angles to the surface.

A modiiied form of pump is shown in Fig. 2. A bulb 21 quite similar tobulb 10 is here used, which is provided with a portion 22 similar toportion 12 of bulb 10. This portion is similarly formed with internalthreads 23 which engage corresponding eX,-y

terna-l threads 24 on a receiver member 25. Member 25 is provided at oneendwith a head 26 identical with head 17 and is formed with a pocket ordepression at 27 in which the discharge is collected. The device isapplied to the nostril in an inclined position instead of vertically, asin the case of the device shown in Fig. 1. In this manner the dischargeis deposited in pocket 27 instead of into the bulb 21.

A still diierent forni of pump is shown in Fig. 3. A bulb 28 identicalwith bulb 10 is employed, to which is secured a stem ineinber 29 adaptedto be engaged and held inV place. in said bulb similarly to the stem 13shown in Fig. 1. This stem is quite short and termlnatesin a portion 30adapted to lbe inserted into a Flexible rubber tube 31.

Tube 31 is Vattachedat its other end to a stem portion 32 similar toportion .30, which terininatesin a spherical head 33v identical withhead1?. This device-diners only from that shown in Fig. 1 `in that thehead is flexibly connected to fthe bulb.

The advantages of my invention are manifest.V The4 device is verysimpleand easy to operate.` t is practicably impossible to tilt the headso that the mucous membrane. is drawn into the same to cause dlscomfort.

neeneoe The ease with which the device may be Y cleanedand'thefew'ness.ofiI the parts render it quite sanitary.

I claim:

1. A nasal suction pump comprising a suction bulb, and a suction headsecured' thereto and in communication therewith, said head having acounter sunk aperture 1n the end thereof fondrawing inv the dis--secretions, said suction head being constrnctedand shaped to t into thenostrilofy a person.`

In testimony whereorl l affix my signature in presence of two witnesses.
